Hybrid Electronic Noise-Cancellation Technology
Your DC ONE-X headset features leading-edge Hybrid
Electronic Noise-Cancelling Technology (ENC) with feed-
forward and feed-back technology for superior active noise
reduction. Feed-forward noise cancelling is accomplished through an
exterior microphone in the ear dome that is isolated from the speaker.
The exterior microphone acquires the noise before it gets to the ear.
Feed-back noise cancelling is performed by the internal microphone
placed near the speaker. The signals are then inverted
to produce a reverse, ‘anti-noise’ signal. This hybrid technology
results in unsurpassed active noise reduction performance.
